Introduction: Effective screening for vitamin D (Vit-D) insufficiency is desirable. Pigmentation of unexposed (constitutive) skin and exposed (facultative) skin can be measured with skin colourimetry to assess dermal capability in synthesizing Vit-D and degree of sunlight exposure respectively. This study aimed at evaluating whether skin colourimetry could be used to screen Vit-D insufficiency among adolescents.Methods: 240 healthy adolescents (mean age=...

Objectives: High resolution peripheral quantitative computed tomography (HR-pQCT) was used to evaluate bone quality and volumetric bone mineral density (vBMD). However, manufacturers only provide a standard protocol for adult but not for growing subjects. The aim of this study was to investigate the difference on measurement between two different HR-pQCT scanning protocols in adolescence with unfused growth plate.Methods: 27 boys and 26 girls aged 13&#15...

Objectives: AIS is a prevalent three-dimensional spinal deformity associated with low bone mass which has been reported to be a significant prognostic factor for curve progression in AIS. If left untreated, low bone mass in AIS could persist into adulthood thus leading to subsequent health problems. This study aimed at evaluating the therapeutic effect of oral calcium plus Vit-D supplementation for low bone mass in skeletally immature AIS girls.Methods: ...
